Privacy

Calculator inputs are processed in your browser and are not automatically submitted to us. No account is required. The site has no advertising.

Analytics

Google Analytics is on by default to show us which calculator pages people use. We send the page path and title, not calculator inputs, results, or URL parameters. Google may process technical information, such as your IP address, and set analytics cookies. You can turn analytics off at any time without affecting the calculators. Change analytics choice

Saved work

Recent calculators, pins, and saved results use local browser storage. They do not sync between devices. Clearing site data removes them, so export a backup when needed. Imported G-code and backup files are read locally.

Shared links

Calculation links contain the inputs you choose to share. Anyone with a link can read those values. Links may remain in browser history and hosting logs. Do not include confidential information. Saved project notes are not included in calculation links.

Site requests

Hosting services process technical data, including IP addresses and requested URLs, to deliver and protect the site.
